警告：在env.rb

之外需要的黄瓜栏基本上，我尝试在我的应用程序中使用twitter-bootstrap-rails和devise gem。但是，当我尝试做rake db:migrate时，它一直抱怨黄瓜。 Gemfile中的黄瓜栏位于group :development, :test之下。警告：在env.rb

我的宝石环境：

user.rb未在app/models /目录中创建。这解决了错误（未初始化的常量User）。黄瓜的警告可以通过什么安德鲁建议

gem 'cucumber-rails', :require => false

或

确保这个存在于为了做到这一点对我的设置features/support/env.rb解决的是以下几点：

rails g cucumber:install 
rails g cucumber:install capybara 
rake cucumber

改变你的Gemfile的条目：

gem 'cucumber-rails', :require => false

看到这些问题：one，two。

我试过了没”工作！ – Billz 2012-03-26 04:47:34

我很抱歉，这会解决您收到的警告，但不会解决“未初始化的常量用户”警告。这是完全不同的，独立的，你真的有两个非常不相关的问题。 – 2012-03-26 04:50:10

user.rb未在app/models /中创建/这解决了错误（未初始化的常量User）。但是，“警告：env.rb以外需要Cucumber-rails”还在那儿。 – Billz 2012-03-26 04:51:26

警告：在env.rb
